Re: 1 rule to turn on AND off?

Possible, yes but perhaps not always desirable in my opinion. It's been a long time since I used the rules engine in the WeMo app. As I remember it though if you have your lights set to switch on at say, time "A" until time "B" then if you decide to switch them off and then on again during the "until" period then the automatic off time "B" time will be ignored. This is because the rule will be cancelled until the next "A" time comes around again.

Using two rules, one for on and another for off solves this problem and your lights will always switch off automatically at your chosen time. Not as neat as having one rule to do the job I know, but it does give greater flexibility.

Re: 1 rule to turn on AND off?

That is no longer the case with "on until" rules. I have a rule that turns on my lights in the morning and then shuts them off once I'm on my way to work. I occasionally snooze the lights back to off for a couple minutes with my Echo before turning them on again. They do still turn off at the prescribed time.
